I'm sure if you just type on them a lot, they'll smooth out pretty quick. My old Thinkpad had shiny keys that almost had the letters worn off from heavy use, but the action was still good. My Macbook Pro has "new" feeling keys, not gritty, but definitely a little bit of texture, nothing unusual. The more I use it, the more I get used to it after the classic IBM keyboard. I find I'm hitting the caps lock key more than usual, and the normal typing position seems just a bit right of what feels natural. But, overall it's a clean design. I'd like to be able to do page up/page down/home/end with single keystrokes.
After using the Macbook Pro for a week, I have to say the trackpad is the best I've ever used on any laptop, period.
